OIL-CAN.l

SPECIFICATION forming part of Letters Patent No. 695,512, dated March 18, 1902.

Application nea capter 14,1901. stanno; 78,559. momias To @ZZ whom it may concern:

Beit known that LWILLIAM SVEIR, a citizen of the United-States, residing at Monmouth, in the county of Warren and State of Illinois, have invented certain new and useful Improvements in Oil-Cans, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to cans intended to contain lubricating-oil to be applied from the4 spout of the can to machinery, and has for its object to provide an improvedcan of this character which can be used as such cans are,

ordinarily used--that is, by tipping the can and pouring oil from the spout directly upon the parts to which oil isto be,applied-and which can also be elnployed by forcibly expelling the oil from the can through its spout,v

so as to cause such oil'to be squirted, and

thereby enable parts not easily accessible to be readily lubricated, such forcible expelling of the oil from the can being also of advantage in cases where the oil is thickened, so asV Referring to said drawings, Figure l is aV longitudinal vertical section; and Fig. 2 is a' horizontal section, at line 2 2 of Fig. 1.

In the drawings, 3 indicates the body of the can, which is cylindrical in form, as usual, and is provided at one side with an ordinary handle 4, suitably affixed thereto.

5 indicates a spout on theside of the can opposite the handle 4 and of ordinary construction and design, such spout being soldered or otherwise suitably secured to the can-body near the lower end thereof and communicating with theinterioljl of the can-body near the base thereof by a suitable opening, which, as` shown, is normally closed by a valve 6, adaptedto open outwardlyfrom the can-body to admit oil into the spout, said valve being held over said opening by a light spring 7. Upon stopping the iiow of oil from the mouth of the spout 5 the weight of the oil in such spout will cause the valve G to be closed, thus retaining the spout full of oil, so that it is ready to flow immediately when the can is next used, as will be readily understood.

8 indicates a piston adapted to iit within and be freely moved up and down Within the can-body 3 and having an opening 9 of considerable size therethrough, which opening is normally closed by a Valve lO, located below said opening, a spring 11, suitably secured at one end to the under'face of the piston, being employed to hold said valve in position. The spring is comparatively a light one, so as to allow the valve to be readily moved away from the opening 9 in order that the oil that is poured into the can from the top may readily pass through such opening to the bot- 'tom of thetcan.

12 indicates a curved strap secured at its ends to opposite sides ofthe piston 8.

13 indicates a piston-rod attached at its lower end to the strap 12,"the special manner of attachment shown being by passing said piston-rod through an opening in the central portion ofthe strap 12 and applying nuts 14 15 to said piston-rod immediately above and below the strap 12, the lower portion of said pistonrod being screw-threaded, as shown, for the attachment of these nuts and for the attachment of another nut.16, which latter nut contacts with the top 17 of the can-body, asshown, and thereby' acts as a li1nit-stop to the VVupward movement of the piston and piston-rod. As these nutsv are adjustablel of courseupon the piston-rod, the piston may be readily and quickly adj usted, as required, within the can. v

18 4indicates a boss in the center ofthe top 17, projecting upward from such top and provided with a removable cap 19. the upper portion of the piston-rod 13 pro- As shown,

jects through a suitable openingjnthe top 17 and through an opening in. the cap 19 in line therewith and is'therebyvfvurnished'with two guiding-supports which tend to maintain it in proper vertical position at allv times. If desired, the hollow boss 18 may be'emp'loyed as a stuffing-box, although I do not" consider such stufngfbox necessary, butprefer, on

they contrary, to have the piston-rod fita ,lit- I tle loosely in the opening in the parts' 17 and 19, as thereby the necessary admission of air to the interior of the can is provided for, which would have to be otherwise provided for if the boss 18 were packed and employed as a stuffing-box.

2O indicates alight coiled spring located beneath the piston 8 and the bottom of the can and acting to normally force said piston upward.

2l indicates an opening through which oil is adapted to be poured into the can, closed by an ordinary removable cap 22.

The can is to be iilled with lubricating-oil through the opening 2l, the weight of such oil as it falls upon the piston overcoming the spring 11, that holds the valve l0 in place, allowing such Valve to turn downward, so that the oil can pass through the opening 9 and fill the can. l/Vith the can filled, oil can be poured from it as from an ordinary can by simply tilting it to allow oil lto flow through the spout 5 upon the part or parts desired, and upon restoring the can to a vertical position to stop the flow of oil the spring 7 will cause the valve G to close the opening at the base of the spout, thereby retaining said spout full of oil, as before described. If upon next using the can it is found that the part t0 `be lubricated is not readily accessible or is difficult to pour oil upon in the way described, such oil can be directed to the proper part by placing the spout in proper position and pressing down upon the head of the piston-rodl, which will forcibly eject a portion of the oil that is below such piston and in the spout out of the mouth of such spout, causing it to be squirted toward and upon the part` desired, the valve l0 of course being kept tightly closed by the pressure against the oil beneath it duringthis operation, as will be understood.

This manner of obtaining oil from the can can also be employed when such oil is too thick to readily flow from the spout when the can is tilted, as in the ordinary use of an oilcan.

By my construction I provide an oil-can that can always be employed as are the ordinary oil-cans, but which has the added advantage of being adapted for use for forcing oil therefrom when force is required or desirable under either of the conditions herein suggested, and this added advantage is obtained by the use of very cheap and simple devices.

That which I claim as my invention, and desire to secure by Letters Patent, is

l. In an oil-can, the combination with a can-body having a discharge-spout, of a piston movable therein and provided with an opening therethrough, a valve on the under side of said piston for controlling said opening, a spring for holding said valve up in place, a spring adapted to hold said piston up, and a piston-rod extending through the can-body, substantially as specified.

2. In an oil-can, the combination with a can-body having a discharge-spout, of a piston movable therein and Ilprovided with an opening therethrough, a valve adapted to close said opening upon the downward movement of the piston, .means for normally holding said piston in a raised position, and a piston-rod extending through the can-body, substantially as specifieth WILLIAM S. WEIR.
